Genetic Progress in Multistage Dairy Cattle Breeding Schemes Using Genetic Markers

Genetic Evaluation of Dairy Cattle in Canada

The calculation and publication of all dairy cattle genetic evaluations in Canada is the responsibility of Canadian Dairy Network (CDN). An 8-member board of directors, the majority being dairy producers, governs this non-profit national organization. Member organizations include all breed associations, milk recording agencies and artificial insemination centres across Canada as well as Dairy F...

Breeding and Genetics: Dairy Genetic Evaluation

Due to the lower DMI, the IH200 heifers had lighter final weight and lower ADG on a live basis (P<.01) than the IHFH heifers, but these differences were reduced on a carcass-adjusted basis. The IH200 heifers had significantly improved feed conversion compared to FH and R200 (P = 0.01) and tended to have better feed conversion than IHFH (P = 0.14) on a carcass-adjusted basis. The IH200 heifers h...

Genetic Diversity between Bali Cattle (Bos javanicus) and It’s Hybrids Using Microsatellite Markers

The aim of this study was to evaluate the Bali cattle genetic diversity and hybrid cattle using microsatellite markers. Blood samples (n=192) were collected from various cattle breed, i.e. Bali (n=96), Madura (n=48), and Peranakan Ongole (PO) Kebumen (n=48). The microsatellite locus used for assessing the genetic variation was INRA035, ILSTS006, ETH225, and HEL9, while the genetic profile was d...

Breeding Cattle for Genetic Resistance to Disease

Breeding and Genetics: Dairy Cattle Breeding I

Humans obtain a number of products from animals. These include food, clothing, medical materials, companionship and research knowledge to name a few. A valued ethic contends that it is inappropriate for one to treat another as a means to an end. In short, it is wrong to treat another as simply a product. Historically, non-human beings have not been included as “others” and thus their treatment ...
